Description of Prepainted Rolled steel Coil for Construction Roofing
Prepainted Rolled steel Coil is a kind of coated steel coil/sheet. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In its coating, Al accounts for about 55%, Si 1.6%, while the remaining is Zn. Aluminum zinc coils enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.
Main Feature of Prepainted Rolled steel Coil for Construction Roofing
1.Corrosion resistance: It mainly depends on the aluminum protection. When the zinc being worn, the aluminum will form a dense layer of aluminum oxide, resist corrosion material to prevent further corrosion inside.
2. Heat resistance: Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperatures over 300 centigrade, and is similar with aluminized steel high temperature oxidation resistance. It often used in chimney pipes, ovens, fluorescent lighting device and the device cover.
3. Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to make insulation materials.
4. Economy: Because density of 55% AL-Zn is smaller than the density of Zn, so in the same weight and thickness of Galvanized zinc layer, aluminum-zinc steel plate is larger area more than 3% of galvanized steel sheet.

- Q: i know that steel helmets werent meant to stop bullets, but i was wondering do they have an value whatsoever for stopping bullets, or is that just yet another thing that hollywood made up(like the omaha beach scene in saving private rian)
- Steel Pot Helmet
- Q: Hi, I would like to know if steel is an important material in desalination plants. If it is, could you specify what type of steel is used (i.e. flat steel products, long steel products, etc). Thanks.
- no u idiot
- Q: I am doing a project on how revolvers work and what materials they use and would like to know what specific grade of stainless steel they use for the manufacturing of the frame and cylinder?
- *Rifle barrels are usually made from steel alloys called ordinance steel, nickel steel, chrome-molybdenum steel, or stainless steel, depending upon the requirements of the cartridge for which they are chambered. The higher the pressure and velocity of a cartridge (pressure and velocity usually go up together), the faster it will wear out a barrel. To give a satisfactory service life, barrels for high velocity cartridges must me made from tougher and harder steel than barrels for lower pressure cartridges. *The 400 (416) series SS commonly known as ordnance grade , is what barrels are made from . *If you want your barrel to be made from super alloy then it is 718 Inconel ,but a costly affair.
- Q: What is the major disadvantage of hardened steel? Do you think this form of iron would be wear resistant and retain a sharpened edge?
- The major disadvantage of hardened steel is that it is very brittle unless it is tempered. Hardened steel would be wear resistant, and would hold an edge as long as you don't cut anything harder than a boiled egg - the impact of the knife on a cutting board would shatter it.
- Q: How are steel coils used in the production of automotive stampings?
- Automotive stampings heavily rely on steel coils, which are vital for their production. These coils are typically crafted from top-notch steel and are cut into specific measurements to meet automotive manufacturers' specifications. To begin the process of using steel coils for automotive stampings, the steel must first be uncoiled. This task is accomplished by a machine called a decoiler, which unwinds the coil and feeds it into the stamping machine. By utilizing the decoiler, a consistent supply of steel is ensured for the stamping process. Once the steel coil is unwound, it is inserted into the stamping machine. Equipped with a die specifically designed for shaping the steel into desired automotive components, the machine commences its work. The die is capable of creating intricate and accurate shapes, such as car body panels, doors, fenders, and structural elements. By applying force, the stamping machine presses the steel coil against the die, forming it into the desired shape. The high-quality steel utilized in the coils guarantees that the stamped components possess the necessary strength and durability required for automotive applications. Following the stamping process, the stamped components undergo a thorough inspection to assess their quality and precision. Any flaws or defects are identified and rectified prior to the components being sent for further processing, including painting, welding, or assembly. In conclusion, steel coils are of utmost importance in the production of automotive stampings. They provide a continuous supply of high-quality steel, which is skillfully shaped into precise and long-lasting automotive components. The utilization of steel coils ensures that the automotive stampings adhere to the required standards for strength, durability, and precision.

You should be able to find plenty of references if you search for these terms. good luck
- Q: How are steel coils inspected for thickness using ultrasonic testing?
- Ultrasonic testing is employed to inspect the thickness of steel coils, utilizing a non-destructive method. When conducting this process, a handheld ultrasonic thickness gauge is utilized to determine the thickness of the coil. The ultrasonic thickness gauge emits high-frequency sound waves that travel through the steel coil. These sound waves rebound from the opposite side of the coil, generating an echo. The time it takes for the echo to return to the gauge is measured and utilized to compute the coil's thickness. The gauge comprises a transducer responsible for emitting the sound waves and a receiver that detects the echoes. To ensure optimal acoustic contact between the transducer and the steel surface, the transducer is placed on the coil's surface, utilizing a coupling gel or oil. The transducer releases a brief burst of sound waves, which penetrate through the steel coil and reach the opposite side. If the sound waves encounter any variations or defects in the coil's thickness, they reflect back to the transducer. These echoes are detected by the receiver, and the time between the emission and reception of the sound waves is measured. By utilizing the known speed of sound in steel, the time taken for the sound waves to traverse the coil and return can be converted into a thickness measurement. This enables an accurate evaluation of the steel coil's thickness at different points. Ultrasonic testing is a dependable and efficient method for inspecting the thickness of steel coils. It permits swift measurements without causing any harm to the material, thereby making it ideal for quality control purposes and ensuring compliance with manufacturing specifications.
- Q: I found the cold steel kukri machete online and I am very impressed and am thinking of ordering it. A friend of mine said that the cold steel kukri machete is nothing compared to the KaBar Kukri Machete. I was wondering if other people who own these machetes could tell me the good and the bad of each machete. Such as what they have been able to cut. If they break easily and such. Thanks in advance.
- cold steel will be thin but made of a carbon steel good enough but not perfect flexable and as for cutting power that varies piece to piece as not all places sell sharpened models so be prepared to hand sharpen in any case you would need to hand sharpen sooner or later so a sharpening stone is a good investment no matter what machete you buycold steel is fine for most peoples need for them unless you see a better price go with either one
- Q: What are the main factors that affect the surface quality of steel coils?
- The main factors that affect the surface quality of steel coils include the quality of the raw materials used, the manufacturing process, the cleanliness of the production environment, the equipment and tools used, and the skill and expertise of the operators.
- Q: How are steel coils used in the manufacturing of electrical enclosures?
- Steel coils are used in the manufacturing of electrical enclosures as they can be formed into various shapes and sizes to create the enclosure's structure. The coils are typically cut, bent, and welded together to form the walls, base, and lid of the enclosure, providing a sturdy and protective housing for electrical components.
